Learning Outcomes:

Candidates should be able to explain and use the terms rate of reaction, rate equation, order of reaction, rate constant, half-life of a reaction, rate-determining step, activation energy, catalysis

Construct and use rate equations of the form: rate = k[A]^m[B]^n (limited to simple cases of single step reactions and of multi-step processes with a rate-determining step, for which m an n are 0, 1, 2) including
1. deducing the order of a reaction by the initial rates method
2. Justifying for zero- and first- order reactions, the order to reaction from concentration-time graphs
3. Verifying that a suggested reaction mechanism is consistent with the observed kinetics
4. predicting the order that would result from a given reaction mechanism
5. calculating an initial rate using concentration data
1. Show understanding that the half-life of a first-order reaction is dependent of concentration
2. use the half-life of a first-order reaction in calculations
Calculate a rate constant using the initial rates method
devise a suitable experimental technique for studying the rate of a reaction, from given information
explain qualitatively, in terms of collision, the effect of concentration changes on the rate of a reaction
Show understanding, including reference to the Boltzmann distribution,of what is meant by the term activation energy
explain qualitatively, in terms both of the Boltzmann distribution and of collision frequency, the effect of temperature change on a rate constant (and hence, on the rate) of reaction
1. Explain that, in the presence of a catalyst, reaction has a different mechanism, i.e., one of lower Ea, giving a larger rate constant
2. Interpret this catalytic effect on a rate constant in terms of the Botlzmann distribution
outline the different modes of action of homogeneous and heterogeneous catalysis including:
1. The Haber Process
2. The catalytic removal of oxides of nitrogen in the exhaust gases from car engines
3. The catalytic role of atmospheric oxides of nitrogen in the oxidation of atmospheric sulfur dioxide
4. The catalytic role of Fe3+ in the I-/S2O82- reaction
Describe enzymes as biological catalysts which may have specific activity
Explain the relationship between substrate concentration and the rate of an enzyme-catalysed reaction in biochemical systems
